💦 Specialist Waterproofing Across Mount Wilson,
Bilpin & the Kurrajong Mountain Corridor
GMG Waterproofing Solutions provides licensed waterproofing, rising damp treatment and remedial rectification throughout
Mount Wilson, Bilpin, Kurrajong and the surrounding mountain areas. Properties throughout this corridor can vary considerably in age, construction, elevation and exposure. Older masonry, changing ground conditions and moisture movement through and around the structure can all influence the waterproofing approach required. GMG assesses the structure, substrate and likely moisture pathway before determining an appropriate waterproofing or remedial system for the property.

Whether the project involves a new wet area, external waterproofing or remedial rectification, our focus is on correct preparation, system selection and installation — not shortcuts.
Waterproofing Starts With Understanding the Structure
Reliable waterproofing depends on selecting the right system for the structure, substrate and exposure.
Correct preparation and careful detailing around junctions, penetrations and terminations help reduce the risk of moisture ingress, premature failure and costly rectification.
